Do most people use a phosphate reactor?

I know in phosphate reactors you can also use activated carbon as an alternative....but what about anything else? Can any other filter media go in it?

whats the highest quality to use for a 150 gallon?


are wave makers un necisary if you have severl powerheads? or do some corals and fish require wave makers?

There is alot of talk about water flow in a tank being as important, if not more important, than the lights.. I get impression people want a tornado in there tanks!!! (well okay, not THAT much). I guess my qustion has to do with the Fish....wouldnt that much water flow disturbe the fish? I know in the freshwater world you dont want too much water flow, like wave makers or someting, the fish would get tossed and bounced around so much they would die! wouldnt too much water motion be stresful and harmful to the fish?
